Specification of Letters Patent.

Patented Feb. 13, 1906.

Application led July 2,1904. Serial No. 215,144.

T @ZZ whom, t may concern:

Be it known that I, HENRY PARSONS, of Marlboro, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Beam- Pressers, of which the following is aspecification.

This invention relates to beam-pressers.

Figure 1 in front elevation shows a machine constructed in accordancewith my invention, parts of the framework being broken away to show thearrangement of my improved adjusting mechanism for the bed. Fig. 2 is anend elevation of a part of the machine, showing my improved adjustingmechanism. Fig. 3 is a cross-sectional view on the line 3 3 of Fig. 1looking toward the bottom of the machine, showing the horizontal rod andthe wing-nuts on the vertical rods. Fig. 4 is a detail view showing theconnection between the horizontal rod and the vertical rod on each sideof the machine. Fig. 5 is a detail view of the double-pawl ratchetcarried by one of the vertical rods. Fig. 6 is a detail view of one ofthe wing-nuts.

1 represents the standard to the framework of a machine of the generaltype shown in United States Letters Patent No. 368,108, to whichreference may be had for the general construction of the machine.,

2 represents a girth or bed on which is arranged a series of blocks 3,that support the material to be cut or died out. ln the practicaloperation of the machine it is necessary to adjust this girth up anddown at different times. Prior to my present invention it has been thepractice to adjust this girth up and down by means of a screw-rod oneither side of the machine, as shown in said Patent No. 368,108. By thisold method of adjustment it was necessary to adjust each end of thegirth 2 separately, which operation involves considerable waste of timeand calls for considerable calculation in order to secure uniformity ofadjustment. By my present invention the adjusting mechanism is all tiedtogether as a unit, so that both ends of the girth are adjustedsimultaneously and uniformly. As shown, this adjusting mechanismconsists of a horizontal rod 4, the ends of which are journaled in a lug5 at either side of the framework.

6 and 7 represent vertical rods, the lower ends of which are j ournaledin the lugs 5, the upper ends being journaled in lugs 8 9, carried bythe upper end of the framework, as

mental beveled shown, the rod 6 being at one side of the machine and therod 7 at the other. The ends of the girth 2 are formed with perforatedlugs 10 11, the rod 6 being arranged in the perforation of the lug 10,while the rod 7 is arranged in the perforation of the lug 11, these lugs10 and 11 being free to move up and down on their respective rods.

13 represents a beveled gear on the lower end of the rod 7, meshin witha comple- 0ear 14 at t e right-hand end of the horizontal-l rod 4. Asimilar gear 15 is secured to the lower end of the rod 6, meshing with acomplemental gear 16 at the lefthand end of the rod 4.

17 represents a nut formed with wings 18. l

There is one of these nuts arranged on each rod 6 and 7, as shown, andengaging screwthreads 2O 21 of said rods. The wings 18 engage planedways on complemental vertical standards 23 of the framework, thuspermitting the nuts 17 to move up and down on their respective rodsWithout turning. As shown, the lugs 10 and 11 rest upon the nuts 17.

25 represents a double-ratchet-pawl mechanism secured to the upper endof the rod 7. By the operation of this pawl 25 in one direction the rods6 and 7 will be turned and cause the nuts 17 to travel downward, thuslowering the girth 2, while a reverse motion of the ratchet-pawl 25 willturn the rods 6 and 7 in the opposite direction, causing the nuts 17 totravel upward, thus raising the girth 2.

By this construction the bed of the machine, consisting of the girth 2and the blocks 3, can be readily and quickly adjusted to any desiredheight. lf for any reason it is desired to adjust one side of themachine separately from the other', the gears 14 or 16, or both, may beslid inward on the rod 4 and the independent adjustment made, afterwhich the gears can be returned to their normal position and secured inplace in the usual way by the pins 30 or other locking means.

Having thus explained the nature of my invention and described a way ofmaking and using the same, although without attempting to set forth allof the forms in which it may be made or all of the modes of its use,what I claim, and desire to secure by Letters Patent, is-

1. In a machine of the class specified, a.

vertically-adjusted bed-frame formed with a perforated lug at each end,stationary ways in each side of the framework in which said IIO lugs arearranged, a vertical screw-threaded rod arranged in each lug, bearingsfor` each end of said rods connected to the framework and separate fromsaid lugs or bed, a horizontal rod, agear upon each endv of said rod, aoomplemental gear on the lower end of each vertical rod, a nut on eachvertical rod under and supporting one of said lugsv and havingprovisions to prevent turning, and a ratchet for turning one ofsaidvertical rods.

2. In a machine of the class specified, a vertically-adjusted bed-frameformed with a perforated lug at each end, stationary ways in each sideof the framework in which said lugs are arranged, a verticalscrew-threaded rod arranged in each lug, bearings for eaeh end of saidrods connected to the frame work and separate from said lugs orbed, ahorizontal rod, a gear upon each end of said rod, a oomplemental gear onthe lower end of eaoh vertical rod, one of the gears of said horizontallrod being mounted to be slid out of engagement with its oomplementalgear, nd connections between said rods and said ugs.

In testimony whereofl I have aiiixed my signature in presence of twowitnesses.`
